Question $2$: $(18$ points$)$ The Aorta splits into right and left femoral arteries as depicted in the figure below. At steady state, blood flows through the system as shown.

a$.(4$ pts$)$ Write the accounting equation for linear momentum that describes this system. Use the stream numbering used in the diagram.

b$.(2$ pts$)$ In the equation above $($a$),$ indicate which terms relate to bulk transfer of momentum versus changes in momentum due to forces applied on the system.

c$.(2$ pts$)$ Does the sum of all forces equal to zero $)=(0$ in this system? Explain your answer in one sentence.
